In Louis Sachar's novel Holes, Stanley Yelnats' family explains its consistent bad luck by the curse placed on his "no-good-dirty-rotten-pig-stealing-great-great-grandfather" by Madam Zeroni for not fulfilling his promise to carry her up the mountain. Stanley therefore feels that it is no surprise that he was in the wrong place in the wrong time and ended up being blamed and punished for a crime he did not commit. However, Stanley's interment in Camp Green Lake eventually turns the family's fortune, as Stanley befriends Hector (Zero), Madam Zeroni's great-great-great-grandson, and saves his (and his own) life by carrying him up that same mountain. During their adventure, Stanley and Hector also discover the bottles of "sploosh," a kind of peach preserves with unique properties, and the treasure buried by Kate Barlow that was also stolen from Yelnats family.
In an interesting twist of the plot, Stanley resolves another curse as well. The Green Lake region has not seen any rain since Sam, a young black man, was killed merely because he was caught kissing a white woman—the village's beloved schoolteacher Miss Katherine Barlow. When Stanley finds Kate's buried treasure, he insists on sharing it with Hector, a poor black boy who has no parents. Finally, the rain falls again in Green Lake, enabling the region to prosper.
